Hi all,
I am planning on building a car port, preferably before the end of this decade.... But I have some design questions.
Size is going to be about 5.5m wide by about 7m long. I was going to support it by 150mm square posts, about 6 per side at approx. 1.6m centers (some design constraints to miss a doorway etc.) Roof was going to be double pitched, so I can collect the water from each side. I also assumed that this would be 'lighter' and allow better run-off than a single pitched roof.
And so the questions (if you please...) - Will the uprights be sufficient? I would brace these against the connect edges along the length to prevent movement.
Some of these uprights will be standing on existing concrete, while one area needs concreting over first - would I be better to get the posts cemented in or use metposts (or similar - I have a mind to get the local fabricators to make something more robust).
For the roof design, my local timber merchant said 2x4 would be sufficient, and it comes in a max of 4.2m lengths - so not sufficient to span it. So with the double pitch, I would have a horizontal joist about half way up - giving greater headroom inside. Within the internal triangle, I would then have an inverted V from the apex, or else a triangular piece of ply in the apex to brace the structure. Any thoughts?
Roof covering - I was planning on ply to provide additional rigidity, covered by roofing felt.
Any thoughts or opinions would be gratefully received!
David.
